以14个甜、糯玉米为研究材料,对影响甜、糯玉米鲜穗产量的8个性状和影响糯玉米籽粒产量的10个性状进行灰色关联分析,结果表明:各主要数量性状对甜玉米鲜穗产量的关联度大小为穗长、穗粗、采收日数、穗行数、穗位高、行粒数、秃尖、株高;对糯玉米鲜穗产量的关联度顺序为穗位高、株高、行粒数、采收日数、穗粗、穗长、秃尖、穗行数;对糯玉米籽粒产量的关联度顺序为千粒重、穗粗、株高、穗行数、穗位高、穗长、行粒数、出籽率、秃尖、生育期。
Based on the gray correlation analysis of eight traits affecting sweet and waxy corn yield and the ten traits affecting waxy corn yield, 14 sweet and waxy maize were used as research materials. The results showed that the main quantitative traits of sweet corn The correlation degree of spike yield was spike length, ear diameter, harvest date, ear number, ear height, line grain number, bald tip, plant height; The order of correlation of fresh spike yield of waxy corn was ear height, Plant height, grain number, harvest date, ear diameter, spike length, bald tip, ear number; the order of correlation of grain yield for waxy maize was 1000-grain weight, ear diameter, plant height, ear number, ear height, Spike length, grain number, seed yield, bald tip, growth period.
